Hi!
I've recently established a synchronized stand-alone copy of Wikidata on a local machine. It's working quite well, but one of the benefits I had hoped to receive from doing this would be an ability to integrate federated queries to other services into queries against Wikidata. I can certainly see from thread associated with Mr. Neubert's message [1] (ref. below) the motivation for disabling remote SERVICE calls on WD's public endpoints, but it would be of great value for me if I could do so in my own private environment.
If you want to run your own instance of Wikidata Query Service, you can do it and then you can allow federated queries. The simplest way to do this is to disable this line:

in the WDQS code and then rebuild it as described in https://github.com/wikimedia/wikidata-query-rdf/blob/master/docs/getting-sta....
